Specification of Letters Patent. Pat t d; S-e 2 1921.

Application filed February 5, 1920. Serial No.'356,472.

T0 allwhomitmay concern. I

Be it known that I, ALFRED L. DAY, a citizen of the United States, reslding at Brookline, county of Norfolk, State of Massachusettshave invented an Improvement in Perforatlng-Machines, of which the following description, in connection with the accompanying drawing, is a specification, like characters-onthe drawing representing like parts. I

This invention relates ,to perforatlng ma-' chines of the type used to perforate characters, such as numbers or letters in paid checks, sales slips, or other sheets of paper,

' mechanism andlock-releasing means which is controlled or actuated by the sheet or sheets of paper which are introduced into the machine into perforating position. I The lock will preferably be so arranged that the withdrawal of the sheet or sheets from the machine will permit the lock to automatically become operative. v lvith my improvement aperson cannot actuate the machine untilhe has first inserted sheetpor. sheets of paper in the machine inposltlon to be perforated.

In order to glvean understanding of my invention. I have illustrated in the draw-i ings a selected embodiment thereof which will now .be described, after which the novel features will be pointedout in the appended claims.

In the drawings, Figure 1 is aside v ew of a perforating machine having my mprovements applied thereto;

Fig. 2 is a section on substantially the.

line 22, Fig. 1. v

My invention may be applied to different types of'perforating machines. and w ll as sume different forms in its different apply cations. Merely for the purposeof illustrating the principle of the invention, I have chosen to show it as it would be used in connection with a familiar type of perforating machine which is more or less commonlyused in banks for perforatlng paid checks and indicating the perforatlons the date of payment. l wish it to be understood, however, that the invention may be applied to other types of'perforating machines.

The perforating machine herein shown is in some respects somewhat similar to that illustrated in United States Patent No.

475,400, May 24,1892. It comprises a base or main frame 1 having in its. front end a horizontal slot or mouth; 2 into which the sheet or Sheets of paper to be perforated are introduced. The under Wall of this slot or mouth 2 is formed by a die-plate 3 having apertures 4 thereln. Situated above these apertures are punches 5 which are vertically movable in'the portion 6 of the frame. The

punches are depressed for perforating the are carried in a swinginghead 8 that is pivoted to theframe at 9. The punches will preferablybe arranged in groups, each group being capable of forming perforatlons indicative'of one character, and there is a matrix member 7 for each group. These matrix members may be in the form of rolls, as shown in said patent, each of whichhas groups. of recesses formed in its periphery. Therecesses of each group are so arranged that the blank spaces between the recesses correspond to the outline of some particular character, and when any matrix is depressed, the punches opposite the recesses will enter the recesses, while those punches whichare opposite blank spaces between recesses" will be depressed into the corre'- sponding apertures 4 in the plate 3 thereby perforating the paper.

The matrix members 7 which are in-the form of rolls can beadjusted to bring different character-forming groups of recesses into position to act on the punches. The actuating movement of the matrix is accomplished by moving the head 8 downwardly about its pivot 9,; and to accomplish this the machine herein shown is provided with an actuating lever 10 which is pivoted'to the head and which is connected to the base by a link 12, said link being pivoted to the base at 13 and pivotally connected at. 14" to a crank disk 15 rigid with the lever 10. The downward movement of the lever'lO will thus force the head 8 downwardly thereby bringing the blank spaces in the matrix '7 paper by means of matrix members 7 which against the punches and actuating them to -produce the required perforations.

The machine herein shown is provided with a strap 16which is pivoted to the base at 17 and at its upper end has a slot 18 in which operates a stud 19 extending from the lever 10.

The parts thus far described are or may be all as usual in perforating machines of' this type and, therefore, it is not necessary to further describe them.

- My invention contemplates means for looking the" actuating member of the perforatin machine and means for releasing the loc: to permit said member to be actuated by the insertion of. a sheet or sheets of paper into the paperre'ceiving slot 2. The particular form of the lock for the actuating member may vary, depending on the character of said actuating member. One simple form of lock is herein illustrated, and it comprises a locking member 20 in the form of a hookshaped lever pivoted at 21 to the strap 16, said lever having the hook portion 22 which crosses the slot 18 and normally prevents downward movement of the stud 19in the slot. Thiswill prevent '{the'actuation of the lever 10. Means are'provided for throw-,

ing this lever into its inoperative position shown in dotted lines by the insertion of a sheet or sheets of paper in theslot' 2; One way in'which this maybe done is by means of'a finger 23 which normally extends across the slot and is engaged by the sheet or sheets of paper as they are introduced into the slot, and by providing suitable connections between this finger and the locking lever 20. This fin'ger 23 is shown "as fast'on a rock shaft 24 whiclris pivoted in. the frame beneath the bed plate 3, and it operates in a suitable openingor recess through the bed plate and in the portion 6 of the frame between the groups of punches.

which is connected by a link 26 to a lever 27 pivoted at 17, and said lever in turn is connectedby a link 28 to an arm 29 extending from the locking lever 20. With this arrangement the depression of the lever 23 by. the insertion of a sheet or sheets of paper in the slot '2' will operate through the conactuate the lever, and the parts will preferably be so balanced that when the paper is o The rock shaft 24 has an arm 25 thereon at one end withdrawn the lockin lever 20 will return to its operative position by the action of gravity. 7 7 V 7 While I have shownv herein one embodiment of the invention adapted to be used in connection with an actuating member in the form of a lever 10, yet I Wish it understood that the construction of the locking member I may vary dependent on the character of the actuating member Without in any way departing from the invention.

A device for locking the actuating member from operation except when the materialto be perforated is introduced into the machine has special advantageswhen used in connection with a perforating machine that is equipped with a counting. device. for recording each actuation of the machine or with a numbering attachment by which the successive actuations are'numbered. In perforating machines having a counter or numbering attachment it is, of course, important that the machine should not be actuated by unauthorized persons because in such case, the unauthorized actuationswill advance the numbering or 'countingmechanism and will, therefore, cause such attachments to make imperfect records."

My invention is, however, capable of gen- ;eral use-in connection with perforating ma,

chines wherever-it is desired to unauthorized operation thereof.

I claim: 1' V prevent any 1. In a perforating machine, the combina tion with perforating punches, of apivoted head carrying a matrix member to actuate i the punches, a lever for moving the head,

means normally locking the lever from operation, and lock-releasing means actuated by A the material to-be perforated as'it is introduced into the machine. I V i 2. In a perforating machine, the, combination with a plurality of perforating punches,

of a pivoted head carrying amatrix member to actuate the punches, a lever for moving the head, a pivotedlatch 'normallyllocking the lever from movement, andmeans actuated by the material to be perforated as it is introduced into the machine to swing the latch into inoperative position. Y

3. In a perforating machine, the com bination with a plurality of perforating punches, of a pivoted head carrying a matrix member by which the punches are actuated, a lever formoving the head, a pivoted latch normally locking the lever from movement,

a lock-releasing finger separate from the latch and situated to be engaged andmoved by the material to be perforatedas it is introduced into the machine, and connections between said finger and said latch whereby movement of the finger will releasethe latch. In testimony whereof, I have signed my name to this specification.

ALFRED L. DAY.
